I have NEVER been able to thread this dispenser. No matter how calm I am, no matter how much I try, it won't work! I've used many rolls and I never am able to use it properly. Please! Make a video before I lose my mind!

Based on all of the rave reviews, I must have received a bad batch or something. I got a small box of these 1.5" cores on the plastic dispensers. I took one small roll (out of the small box of them) with me to a convention, so that I could pack up everything when the show was complete. When I put it on the first box, I noticed that something was very wrong. It would barely stick to the box. I noticed that it would barely even stick to my fingers. I then tried to seal a couple boxes with it. However, buy the time I got to the next box, it was already coming off of the previous box. When pulled it off of the roll, it was nearly as sticky on the "adhesive" side as it was on the back. This was huge mess for me. It was the only roll of tape I had (I only had 6-7 boxes to seal). When I got back, I noticed that the other brand-new rolls were the same. Very disappointing. :-(
